JennAir Oven / Range Error Code F3E0
Oven temperature sensor open
Common Causes
- 1RTD probe failed open
- 2Rear sensor connector loose
- 3Sensor lead heat-damaged
Step-by-Step Troubleshooting
- 1
Unplug the range and reach the RTD probe where it enters the rear wall of the JennAir cavity, held by one or two screws
- 2
Disconnect the probe and measure resistance, expecting roughly one thousand eighty ohms at room temperature
- 3
An over-limit or infinite reading confirms an open probe that should be swapped as an assembly
- 4
Check the harness inside the cavity for heat-cracked insulation before assuming the probe alone is at fault
Pro Diagnostic Tip
The JennAir RTD rises in resistance with heat, so a probe that measures right when cold but drifts once the V2 convection element warms is failing internally — replace it even if the cold check looks fine, and inspect the harness first since a wire repair can save the sensor.
